Patent Pending

This BCG enables you to run a standard 3 oz standard carbine buffer instead of H buffer weights with an FRT.

There is a floating weight in the carrier tail which has a dead blow effect eliminating bolt bounce, and providing enough weight for the FRT to function as intended. 

We have tested this successfully with the Hoffman Tactical Super Safety, AS Designs ARC fire FRS, Atrius Development FRS, and Rare Breed FRT. Similarly designed product should work as well.

    Finally. FRT running

    Posted by Hans on September 20, 2026

    5 months of frustration is over. H1, h2, h3, geissele h1 super 42, gas block adjustments. Found this, wnt back to original ruger carbine buffer and spring- perfect. The gas block dials it in perfectly. Thank you kak geniuses.

    Works as described. One of the best accessories for the firearms market since the FRT. Absolutely AMAZING. Works great with me H&R M16A2 with C.A.R.L. 3-round burst system. Hoping to see a 9mm version soon.

    Dbc bcg works pretty well. Pin walks though

    Posted by Chris on September 13, 2026

    Works pretty well and does what it is supposed to. Used it with a H3 super 42 and it slowed it down enough to get the perfect fire rate. The only thing is the roll pin that holds the weight wants to walk out. Id imagine it cant escape but it was sitting proud of the carrier after 200rds.

    I love it!

    I was tired of trying to fine tune my 300 blackout to run with a trigger kicker. I swapped the kicker out for a super safety and it ran ok but still had problems with subs after numerous springs and buffer weights. I threw this in with carbine spring and h2 buffer just because and I have no complaints. GET ONE! I shoot suppressed and was told a down vent was the better option but I have no issues

    The Triggered Company's Disruptor FRT drop in trigger group didn't work with a H3 5.4 oz buffer....but worked like a champ with this KAK BCG. Nothing but praise from me!!! Easy FRT tuning with one try. AWESOME!!!
